Agileload is an enterprise class performance testing tool. With Agileload you can create complex test scenarios in minutes, generate load in-house and from the cloud, monitor in real time your back-office performance, get insights and recommendation of your performance bottlenecks, create custom reports. Agileload is free for download, scripting and small tests. Extra load can be rented on the website. Cloud load testing and technology specific performance monitors are included in the free package.

The Web Performance Load Tester is a performance testing tool for websites with an automated record and config process that cuts load testing time by up to 80%. And there's no scripting language to learn. The automated analysis tells you exactly how many users your website can handle while locating operating system and application server performance problems in CPU usage, memory usage, and disk and network I/O. It works well with most web technologies including AJAX.

The Ajax View approach is to insert a server-side proxy (or web server plugin) in-between the web server machines and the end-user's browser. This proxy captures the web application's JavaScript code as it is being sent to a browser and rewrites the code to insert extra instrumentation code. The injected instrumentation code runs with the rest of the web application inside the end-user's browser and can capture performance, call graph, application state and user interaction information, providing visibility directly into the last hop of the user's experience.

AlertFox is a revolutionary new self-service website transaction monitoring service that is capable of keeping tabs on the functioning and performance of all websites, even sites that use AJAX, Flash and Silverlight.

AMD CodeAnalyst™ Performance Analyzer is a suite of powerful tools that analyze software performance on AMD microprocessors and help developers optimize application performance. It uses a profiling technique to identify performance areas and issues within the system. Using this suite of tools, developers can get visibility into overall system performance, and can navigate into different modules and functions to locate hotspots within the target application.

This is the Box Anemometer, the MySQL Slow Query Monitor. This tool is used to analyze slow query logs collected from MySQL instances to identify problematic queries.

AnyDbTest is declarative style testing tool. We need not to program any more. What we do is to express what we want to test, rather than how to test. We only need to write an Xml test configure file to tell AnyDbTest what we want to test. Rather than painstakingly writing test code for xUnit test framework. So AnyDbTest is the right choice for DBA or DB developers.

Apache JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

AppLoader is a complete load, stress, regression and functional testing software from NRG Global.It examines the application’s reliability under extreme load conditions by simulating any number of end users interacting with applications in real-life scenarios. AppLoader is script-free, protocol independent and supports a wide variety of web and enterprise class applications. It generates customizable real-time reports, charts and alerts for clear and accurate performance monitoring.

Autobench is a simple Perl script for automating the process of benchmarking a web server (or for conducting a comparative test of two different web servers).
